Access denied error to .content after moving project

After moving my project code (and all hidden folders) to a different folder, when trying to add to the Object Repository I am getting this error:

I had to delete the entire .objects folder, losing what I had already done, and then it recreated the .objects folder when I reopened the project and started adding to the Object Repository.

Is it a network location? If so some security policies might be active, restricting access. Please check folders and files security settings from windows explorer.

I have full access to where I moved it to, since I was able to move it to there.
